Variable for question types

I am not all that familiar with java scripting; however I have done the following before on test questions:After creating a question, I have also placed a "Process Question" button on the page. When this button is clicked its action is to process the question but I also have another action placed on it that Modifies my variable to a value equaling one (using Set Variable Contents) if the question is correct.When the user clicks the NEXT button to move on, I have an action on it that checks for the variable name to be equal to one. If it isn't it won't allow the user to move forward and if it is equal to one than they move on to the next page or question.I am sure you could use something similar to create your number of tries and then let the user move on.
